Classify each polynomial based on the number of terms it contains.

see explanation

Step-by-step explanation:

A monomial is an expression with one term

A binomial is an expression with 2 terms

A trinomial is an expression with 3 terms

Thus

- 2x² - x + 3.5 ← has 3 terms, hence trinomial

10xyz³ ← has 1 term, hence monomial

- x²y² + 2y ← has 2 terms, hence binomial

8x² + 0.25 ← has 2 terms, hence binomial

x³ + 2x²y - 3x ← has 3 terms, hence trinomial

a 10 percent increase

5+2x=a
